SPECIFICATION forming part of Letters Patent No. 393,397, dated November 27, 1888.

Application filed September 20, 1887. Serial No. 250,187. (No model.)

' To aZZ whom it may concern.-

Be it known that I, CASPER F. SEARCH, a citizen of the United States, residing at \Vinona, in the county of Winona and State of Minnesota, have invented a new and useful Improvement in Harvesters, of which the following is a specification;

My invention relates particularly to an improvement in that portion of the mechanism to of a self-binding harvesting-machine, wherein means are provided for straightening the grain in delivering it to form the gavel by accelerating the motion of the butt-ends of the grain or retarding that of the heads, or both.

The object of my invention is to provide improved means forthe purpose, of simple construction and thoroughly effective in op eration.

My invention consists in the construction of the butt-accelerating mechanism.

My invention also consists in providing spring-arms underneath the shield, extending toward the deck below the shield, to retard .the headends of the grain; and it further 0011- 2 sists in details of construction and combinations of parts, as hereinafter more fully set forth.

In the drawings, Figure 1 is a broken longitudinal sectional end elevation of so much of a self-binding harvester as will serve to illustrate my improvement, with which it is provided; Fig. 2, a broken view in elevation of the opposite end of the machine from that shown in Fig. 1; Fig. 3,an enlarged view in on er 5 side elevation of the deck surmounted by the shield, shown broken away to display the spring-retarding fingers provided upon it and the butt-accelerating device; Fig. 4, an enlarged view showing the frame or housing and 0 the parts carried thereby; and Fig. 5, a section taken on the line 5 5 of Fig. 4,viewed in the direction of the arrows,and showing parts in elevation.

A is the upper roller ofthe top apron ofthe elevator,and B the upper roller ofthelower apron, both being automatically and simultaneously adjustable in slots 1" and g at one end and r and at the opposite end by means of bars 19, forming apron-guides, which slots and levers,how-

5o ever, form no part of my present application,

but of another application of mine, Serial No. 250,189, filed simultaneously with the present, and wherein their function and manner of operation are clearly set forth.

Through a slot, 0, in the forward side of the frame of the machine below the upper end of the deck C, a short rotary shaft, or, is inserted, carrying at its outer end a sprocket-wheel, D, driven from a similar wheel, D, on the end of the roller B by a chain connection, in. The shaft n is supported at its inner end in a strap. n,extending downward from the under side of the deck and carrying a stationary cog-wheel, Z, centrally through which the shaft it also extends.

E is a frame or housing open on one side, as shown, and comprising a central or body portion, 00, having four arms, x, :0 a2, and 03*, extending at right angles to each other from the central portion, at which it surrounds and is secured to the shaft a. Around the central portion, 00, of the housing or frame E are cogwheels 1, 2, 3, and 4, supported to rotate on axes, one at-the base of each arm w, m m and x", where they surround the central stationary 7 5 cog-wheel, with which they correspond in size, andare also in mesh with the latter. Near the outer ends of the arms of the housing E are rotary cog-wheels k, k k", and h (the first named being obscured from view in Fig. 1 by the bearing a,) all of one size and corresponding with the cog-wheels 1, 2, 3, and 4, with which they are respectively in mesh, and the cog-wheels k, k, Id, and k carry each a finger,

F, rigidly secured to its inner face, or forming part thereof, as shown. The deck C is slotted,

as shown at i, Fig. 3, in line with the fingers F at the part where the elevator discharges the butt-ends of the grain, and the slot is covered by a correspondinglyslotted convex 9c shield, G, to cause the grain to pass readily over the slot.

H is the shield supported over the deck 0 on a rod, h, in a bearing, h, extending from the breast-plate I of the knotter mechanism 5 and adjustable in the slots r W, like the deck.

0, with the rollers and platform, as and for the purpose set forth in my aforesaid concurrent application. On the under side of the shield H are light easily-flexible spring-fingers r00 K, adjustable in holes r provided in the shield II to receive them, being secured by boltsf, nutsf, and washers f", which securing means also renders them readily removable; and the springfingers are bent, as shown in Fig. 1, and extend near the surface of the deck 0.

Several holes 9 may be provided in line with each other, as shown, to permit transportation of the spring-fingers, and other means than those shown and described may be en ployed as the releasable sccnrin g means of the spring-fingers. I do not, therefore, wish to be understood as limiting myself to the employment of any number of holes 7, nor to the par ticular ilngcrsecuring mechanism.

The operation of my improvement is as follows: The connection of the sprocket-wheels D and 1) causes the housing or frame E to be rotated by the rotation of the apronroller B aboutthc central stationary cogwheel, l, which rotates the fingers F by the gearing connecting them with the center stationary eog'wheel. The fingers are originally set to extend in parallel planes in the same direction, and, as will be seen from the nature of the mechanism, each finger while it makes a complete revolution with that of the frame or housing E is parallel in each position assumed by it to itself in a preceding position. Thus as each finger enters in turn the upper end of the slot 2' it extends to its full limit at or near the center of the slot, and after reaching its limit of ex tension in leaving the slot at the lower end of the latter it recedes with a species of waving motion, whereby it forces the butt-ends of the grain downward upon the slanting deck without binding it, as it would were its motion imparted directly from the center to cause it to rotate with the shaft in. \Vhile the fingers F, in extending through the slot 17, accelerate the butt-ends of the grain for the usual purpose, the spring-fingers K retard the grain toward the head ends, and thus cause it to be delivered in proper position to form the gavel. The rotating-finger device may, however, be employed without the retardingfingers, and vice versa, though I prefer in my particular machine to use them together for the sake of their cooperation.

The term frame or housing herein employed is intended to be sufficiently generic to include any suitable rotatory support for the cog-wheel gear.

Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a self-binding harvestingmachine, the combination, with the butt-end of the deck, of a shielded slot, 2', a rotary shaft, a, a stationary cog-wheel, Z, a frame or housing, E, secured to the shaft a to revolve with it, cogwheels 1., 2, 3, and 4, supported to rotate on the frame or housing around the stationary cog-wheel and in mesh with the latter, rotary cog-wheels 7r, 7.", h", and it", supported on the frame or housing and respectively in mesh with the cog-wheels l, 2, 3, and 4, and fingers F on the cog-wheels k, k, 7.1, and 7c, rotated by the revolution of the frame or housing and maintained by the intermeshing cog-wheel gear parallel to each other and at a uniform angle to the plane of the deck throughout their rotation, and thereby extended consecutively through the slot in the shield G to accelerate the butt-ends of the grain, substantially as described.

2. In combination with the butt-end of the deck of a self-binding harvester provided with aslot, the device for advancing the butt-ends of the grain, comprising a revolving frame or housing, E, carrying-fingers which extend through the slot consecutively as the frame or housing revolves, and a system of intermeshing cog-wheels, substantially as shown, rotating the said fingers in a direction contrary to that of the frame or housing, whereby the fingcrs are always maintained parallel to each other and at a uniform angle to the plane of the deck, a shield, H, supported over the deck, and spring-fingers K, secured to and extending from the shield toward the deck to retard the head ends of the grain, substantially as described.

3. In a self binding harvester, the combination, with the deck and shield supported to overhang the deck, of springfingers K, secured to and extending from the shield toward the deck to retard the head ends of the grain, substantially as described.

4. In a self-binding harvester, the combination, with the deck and shield, the lattcrhaving openings 9, of spring-fingers K, rcmovably secured in the said openings and extending from the shield toward the deck to retard the head ends of the grain, substantially as described.
